I looked around for Scruffy's post where he posted a YouTube video of the final show of DALS 2016 in Nice. It was a video taken by SkeLeton who attended the event. It is a fairly long video where all the participants dance and greet the crowd. The link he posted took you near the end where Alizee and Greg are interacting with each other, and of course Alizee is being silly as ever.
I could not find the post, so I am just responding to it here.
I never watched it from the beginning until the other day, thinking that the first six or seven minutes up until that point where Scruffy specified would be uninteresting. I was wrong about that because Alizee sings a little bit. She sings part of the song "Fame" in English, does a quick dance with Greg, and sings a little more. She sounds great. She also gives us a bonus face scrunch at 4:19.
